A fluorescent light tube that has been evacuated and has a volume of $300\,\text{cm}^3$ is then filled with a gas at $300\,\text{K}$ and $101\,\text{kPa}$. As a result, the tube’s mass rises by $1.02\,\text{g}$. The gas follows the ideal gas equation $pV = nRT$. What is the identity of the gas?
- Aargon
- Bkrypton
- Cneon
